COUNTY GENERAL HIGHWAY MAPS

These maps were produced by the Kentucky Department of Highways. The
originals are 1:125,000 scale and about 18 inches by 18 to 24 inches
(some are a little larger and a few are oriented 90° from the
others). Two series are available: 1950 and 1999. The 1950 series maps
were often actually from the 1930s and 40s with only minor updates. A
few of the 1999 series maps are from earlier in the 1990s.
(See the
notes
below for more information about how the maps were scanned and
processed.)

The General Highway Maps are no longer updated and they will be
replaced by the new County Road Series. The State Primary Road
System maps are available for each county now, but they contain less
detail. See the
Kentucky Transportation Cabinet's
web site for more information.

NOTES

The 1950 files were scanned at the University of Kentucky Map Library
at 300 dpi and black-and-white (1 bit). They range in size from about
3 to 5 megabytes.

The 1999 files were scanned by the Kentucky Department of Highways with
additional processing at the University of Kentucky Computing Center.
The maps were scanned at 300 dpi and 8-bit gray scale and reduced to
4-bit. They range in size from about 1 to 4 megabytes.

The 1999 GIF images were converted to 72 dpi, scaled 50%, and reduced to
4-bit gray scale. The resulting 72 dpi, 16-gray-level images are about
208% of their original size. This size is useful for direct display on
most computer monitors, as a template for drawing programs, and can be
printed at 150 dpi to yield a usable, although slightly fuzzy, map that
is about 4% larger than the original. Printing at 192 dpi will yield a
map about the original size. They range in size from about 256 kilobytes
up to a little more than a megabyte.
